This paper considers a one-sector overlapping-generations model with production. We observe that under standard assumptions on preferences and technology, the perfect-foresight equilibrium violates positivity constraints for large sets of initial conditions. The consideration of the positivity...

We examine the behavior of the real exchange rates of nine transition economies during the 1990s. We propose an empirical model rationalized on the basis of standard economic models in the tradition of Mundell-Fleming-Dornbusch and Harrod-Balassa-Samuelson, allowing explicitly for real interest...

Summary Evidence on the role of chaotic and nonlinear dynamics on labor markets is mixed. It is unclear whether nonlinear relationships are responsible for the dynamic patterns observed in Europe during the past decades. In this paper, we test German labor market data for the null hypothesis of...

Many past studies documented a strong evidence of a linkage between stock prices and macroeconomic activities across different stock markets and time horizons. However, most of these studies have focused on developed economies and highlighted the impact of either domestic variables or a few...

Linear asset-pricing relations, with macroeconomic factors as state variables, have found wide usein empirical finance. Applications of such relations range from academic studies of market efficiency andmarket anomalies to practical uses such as risk management and estimation of the cost of...

Summary The asset price channel focuses on the relative prices of a wide range of assets in the transmission of monetary impulses on the financial and real capital markets. If monetary impulses are already fading on the financial markets, then their effectiveness in terms of economic policy...

Summary Models with heterogeneous interacting agents have proven to be quite successful in the past. For instance, such models are able to mimic the dynamics of financial markets quite well. The goal of our paper is to explore whether this approach may offer new insights into the working of...

The American savings rate, always low by international standards, has fallen sharply in recent decades. In this essay, I argue that a large part of the savings shortfall results from pressures to keep pace with community spending standards, pressures that have been exacerbated by rising income...

Standard economic intuition of revealed preference implies that when two parties freely enter into a contract then neither should be worse off. In this study, we develop a simple model showing that introducing the opportunity to contract can lower welfare for some, and perhaps all, contracting...
